The purpose of this study is to consider debates the reorganization of administrative districts and to investigate the role of maps in this debate during the early stage of French Revolution. For this, firstly, we examined the argument of reformers who attempted to change the administration system of the Old Regime. We found that physiocrats proposed map use for their attempt to reform this system. Secondly, we considered the debate on the theme of the new division of the kingdom on the basis of speeches or interventions delivered to the National Assembly. Robert de Hesseln's map, itself influenced by the geometric spirit shown by the map of Cassini, played an crucial role in the utopian ideas of revolutionaries who would divide France in administrative units of equal size geometric grid. Thirdly, the deputies decided the number and boundary of department on the basis of Hennequin's map. The final cut which resulted in very tense negotiations with local leaders was irregular polygons modeled on patterns of economic relations, and elements of relief and historical tradition. Fourthly, new administrative divisions are plotted on the map of Cassini and presented to the National Assembly. And it was declared as a new administrative division of France.

Primary culture of cerebellar neuronal cells derived from 8-day old Long-Evans rats was used. Pure granule cells, astrocytes or mixed cells culture systems were prepared. These cells were differentiated and developed synaptic connections. And the astrocytes were identified by immunostaining with glial fibrillary acidic protein (GFAP). Methamphetamine (MAP), which acts on dopaminergic system and cadmium (Cd), a toxic heavy metal, were applied and biochemical assays and electrophysiological studies were performed. $LC_50$ values estimated by MTT assay of MAP and Cd were 3 mM and 2$\mu M$ respectively. Cells were treated with 1 mM or 2 mM MAP and 1$\mu M$ $CdCl_2$ for 48 hour, and the incubation media were analyzed for the content of released LDH. MAP (2 mM) and Cd significantly increased the LDH release. Cell viability was decreased in both groups and some cytopathological changes like cell swelling or vacuolization were seen. The cerebellar granule cells were used for measuring membrane currents using whole-cell clamp technique. Sodium and potassium currents were not affected by MAP neither Cd, but calcium current was significantly reduced by Cd but not affected by MAP. Therefore, in vitro neurotoxicity test system using neuronaI cells and astrocytes cultures were established and can be used in screening of potential neurotoxic chemicals.

Recently, issues regarding underground safety such as sink hole, ground subsidence and damage to old underground facilities have been increasing in urban areas, raising the need for more accurate management of underground facilities. Thus, this study derived a technique for comparing spatial data of underground facilities acquired from GPR exploration results acquired at the site with spatial data of integrated underground spatial maps. Using this underground space integrated map-linked service prototype program developed through this study, comparing the location information of the GPR exploration results and the underground space integrated map for the verification of site usability in some sections around Gangnam Station, the results demonstrated that the location of the map is 0.879m maximum, minimum of 0.101m and the average fudge factor was 0.625m. If accuracy of the GPR exploration results is guaranteed, it is judged that it can be used to improve the location accuracy of the underground space integration map.

This study aims to clarify the transformation of urban spatial structure around old castle in cheong-ju city. The urban spatial structure is composed with road system, block division, and lot system with original cadastral map in 1913 and 2011 GIS. Transformation of road system is classified into control of road line, construction and extension of road. Construction of arterial road was divided into Nam-juro and Mang-sunro with 2 blocks and lot system was destoyed. Transformation of block has not been developed except 4 blocks. The 4 blocks were divided into east-west or north-south direction and became 8 blocks. Transformation of lot system is classified into maintained, subdivided, and destroyed lots in shape and size of lots. Maintained lots were found in large lot in size for public office and park. Subdivided lots were mainly represented with the existing main road, an active alleys, and so on. Destroyed lots by road construction and extension were showed in Nam-juro. Although all these transformations are used to enhance urban spatial structure. The old systems have remained around old castle in cheong-ju city.

This Hee Kyeong Ru, a kind of "Nu-Gak" in Gwangju is a high storied old government official building memorizes the recovery of Gwangju area reputation. Hee Kyeong Ru, literally means, delightful and happy occasions. This kind of the buildings were build for the receptions and the banquets for the high government officials in travelling areas to areas. It provided very high formality as compared to the buildings in the mountains. Nu-Gak buildings have a lot in common, since they had been constructed under the influence of the then time period and for the common reasons. Several records about Hee Kyeong Ru can be found in the old literatures, poetries, pictures and atlases. Also, we can see the shape of the building and the location through the mark in the old map. According to the historic materials, Nu-Gak buildingsof other old goveenment offices with Hee Kyeong Ru are similar to that of the size and construction. So we can draw the common points of the existing old official buildings and could assume the original form of Hee Kyeong Ru. In conclusion, we need to restore Hee Kyeng Ru as the historical meaningful building and use it as a representative cultural building in Gwangju.

The goal of this thesis is to make a comparative study about the variant form of the Chinese character in the five sorts of old maps drawing outside of the main gates of old map including DeDongYei-jido. The main task of this thesis can be classified under three heads - (1) introducing the literature of comparative study in the five sorts of old maps including DeDongYei-jido (2) classification of variant form in the five sorts of old maps (3) characteristic of variant form in the five sorts of old maps. In this thesis, aspect of variant form is classified under six head - (1) variation of the whole shape of the character (2) taking place the variation in both sides of Chinese character (3) taking place the variation in part (4) taking place variation in the strokes of the Chinese character (5) misusing different characters (6) changing different characters. This thesis explains some characteristic of variant form - (1) simplification of the shape of characters (2) using the Hou-qi-zi(後起字, Chinese character which is actually the same but made the next) (3) replacing the overlapped both sides of Chinese character with omit mark (4) a wrongly written character (5) discovering the variant form such as variant form of 廣, 广 variant form of 廛, variant form of 院 which was not recorded in Chinese literature. From now on, there should be some collections of variant form of Korean style and study. we are going to have to standardize aspect of variation and rule of variant form in old maps until we have to make some ways to recognize the block letter.

The purpose of this study was to minimize the forest disturbance around an entry road of a power transmission tower construction site between Taean and Sinsesan, Chungnam. The main study field was classified into existing materials and a GIS, remote sensing analysis, and a field examination. This information was used to identify the most suitable entry road using a degree of green naturality map, eco-naturality map, actual vegetation map, and a forest state map as the existing materials. Also, the study used an normalized difference vegetation index, altitude and slope map in order to make the evaluation materials which used an remote sensing image, and GIS. This data was used to choose an optimum area, and diagnosed the current condition of the vegetation with a field survey of the area. It analyzed vegetation structure, species diversity, the age of trees in a field examination. Subsequently, we proposed four area types based on the analysis results--preservation area, transplantation area, restoration area and development area. As a result, the preservation area was categorized into 8 grades, according to the degree of green naturality, large area of breast diameter at Pinus densiflora community, competition area of Pinus densiflora and Quercus spp. and Quercus spp. community of over 20 years old. A transplantation area established 46 optimum areas according to the GIS analysis and vegetation investigation results. Vegetation restoration plan for disturbance area should be made based on ecological value of existing vegetation to worthwhile area as Quercus spp. mixing forest proposed. The development area selected a ecological worthless place as an artificial forest where Pinus densiflora and Pinus thunbergii growth is poor. This research results suggest that restoration of vegetation will be possible in the real world. Also, ecological restoration guidelines will be made through building and analyzing data base and routine monitoring of transplantation and restoration area.

Life of building repeats removal and new construction continuously because it is limited like living things. But, because the physical standard is subjective and abstract, saying too much is not even though it had been influenced by policy decision of the government. To solve these problem clear data about superannuation degree of building after construction accordingly decision relationship necessity continuously rise. To above background, this study on the Constructing Database Based and Improvement of Old Building using GIS in Busan. The results are as following. First, presented necessity of knowledge information gap mitigation. Second, present Busan's ordinance detailed Contents of old-badness building and production-consequences.

Old Russian Legation(1890) has been attracted public attention in terms of politics and foreign affairs than architectural style because of conditions of location and historical incident. Though it was heavily damaged during the Korean war, and only the tower has been restored, it is very important in architectural history in Korea, because it is the oldest western style brick building which is existing with the old bishop's house in Myeong-Dong. But it has been impossible to reveal exactly the original form as there has been few reliable materials(picture, drawing, document) and it's remains were nearly destroyed owing to development of the surroundings. Recently the decisive document(site outline map) was found, and new research on the architect Sabatine was studied. So I can get into close with the original form by the results. In this study, I tried to conjecture the original form of the old Russian legation(the size, style, plan and indoor space, arrangement of attached facilities) and I checked the location and structure of the room where King Gojong stayed when he took refuge, and the use of the passage in the basement.

Hydrological characteristics would be utilized to apply such as hydrologic modelling or basin management. This study is to extract hydrological characteristics through DEM and stream network analysis using a hydrologic unit map and digital topographic map in Milyang river basin. OEM and stream network was generated from digital topographic map. Especially stream network was allowed direction, stream order, and topology. As a result of the study, it shows that Milyang river has been changing geologically mature stage into old phase and the landform of Milyang river correspond to Horton-Strahler's law on morphology of stream. This methodology can be applicable to other areas related to hydrological characteristics with vector data.
